ROBERT B. CARSLEY, OF NEW IBEDFORD, MASSACHUSETTS, ASSIGNOR TO THE TRIUMPH HEAT AND LIGIIT COMPANY, OF PORTLAND, MAINE.

BURNER.

SPECIFICATION forming part of Letters Patent No. 417,541, dated December` 17, 1889.

' Application filed May 22, 1888. Serial No. 274,659. (No model.)

To all whom it may concern.- Be itknown that I, ROBERT B. CARsLEY, of New Bedford, county of Bristol, State of Massachusetts, have invented an Improvement in Burners, of which the following description, in connection with the accompanying drawings, is a speciflcatiomlike letters on the drawings representing like parts.

l This invention has for its object to provide Io a burner or heating apparatus in which gas or vapor fuel maybe safely and economically consumed with a maximum yield of heat, my improved heating apparatus or burner, among other things, being especially adapted x5 to be used in stoves or ranges of ordinary construction as now commonly made.

The particular features of my invention.

will be point-ed out in the claims at thc end of this specification. zo Figure 1 is a side elevation of aheating apparatus embodying my invention; Fig. 2, an end vview of the apparatus shown in Fig. l; Fig.3, a top or plan view of the apparatus shown in Fig. 1;. Fig. 4, a section of the hotair chamber on line x, Fig. 8; Fig. 5, an

isometric view of the hollow base or reservoir detached'and partially broken out; Fig. G, a vertical section of one of the independent burners detached; Fig. 7, a top or plan 3o view of the nipple; Fig. 8, an under side view of a muiile for the independent burners; Fig. 9, a top view of the independent burner with the muffle removed.

The base or reservoir A, cast, as herein shown, to leave air-spaces A', (see Fig. 5,) is hollow to receive gas or vaporfuel admitted therein by inlet-pipes a., one at each end, only one being shown in Fig. 5, the said hollow base or reservoir being divided transversely, 4o as herein shown, to form two compartments or chambers A2 A3. The top or upper face of the hollow base A is tapped to form gasoutlets a', into each of'which may be screwed the shank a2 of a hollow nipple a3, forming the base or support of an independent burner, composed, essentially, of an inner tube or pipe d4 and outer tube or pipe a5, of wirenetting or other foraminous metal, fitted upon the said nipple. Each independent burner 5o is provided with a muile composed of a prefer( bly metal plate b, having lugs b on its under side to t between the outer and inner tubes of the burner to retain the mufiie in place. The muftle causes the gas or vapo-r passing up the burn er to pass laterally through 5 5 .and outside of the tubes, where it is commingled with air, thereby obtaining a more perfect combustion.

The base A supports uprights b3, which sustain above the independent burners, prefer- 6o ably, a metal casting b4, forming a hot-air-radiating chamber or equalizer, by which the heat generated by the burners is spread out over a substantially large area. The casting b4 is made hollow, and has its top and bot- 65 tom provided with holes or openings b5, having walls extended through the said casting, the Asaid holes constituting'gas-outlets, through which passes the greater portion of the heat from the independent burners lo- 7o cated below the said holes. The casting is also provided with holes h6, which communicate with the interior of the casting and form air-holes.

I have herein shown the burners located near the sides of the base, and consequently the gas-outlets in the casting near the center thereof; but I do not desire to limitmyselt to any particular arrangement ofthe burners on the base or reservir.

The base or reservoir is divided by the wall d into two compartments, so that only onehalf of the heating apparatus may be used at one time, if desired; but it is evident the said base or reservoir may be divided into any desired number of chambers or compartments, each having a suitable gas-inlet controlled by a suitable cock. Before any of the burners are lighted the gas admitted to the compartments of the reservoir is under normal press- 9c ure; but after lighting one or more of the said burners the pressure of the gas so stored is increased by its rarefaction due to the heat of the lighted burner, and thereafter the gas passes to the burners under an increased head or pressure over that in the inlet-pipe, which head, being substantially constant, aifords a steadier and better flame. Theouter tube is cut, as at c, and the cut portion bent outwardly to form an air-inlet, by which air is admitted roo between the outer and inner tubes.

In operation let it be supposed that gas has been admitted tothe burner and ignited. The gas is prevented from passing directly upward by the mule, and consequently it must pass through the foraminous tubes; but it cannot pass through the inner tube, as a current of cold air is constantly passing up the inner tube; hence it must pass through the sides of the outer tube. The current of cold air meets the mufiie and is forced back, it being made to seek another outlet, which is through the sides of the foraminous tubes. The air commingles with the gas between the outer and inner tube and combustion takes place; but, owing to the force of the cold air in the inner tube and the draft formed by the combustion of the gas, some of the gas which is unconsumed is forced through the outer tube, where it is consumed, the oxygen being supplied by the air on the outside of the burner. The llame arising from the combustion of the gas is diffused or spread out laterally by the edge of the muflie ovfrlapping the outer tube, the said flame passing or .folding over the inutile and concentrating or meeting substantially above the center of the said muitle, thereby obtaining a maximum heat at. that point, which point, as herein shown, is substantially in line with the openings b5.

A burner composed, essentially, of an inner and outertubcr of foraminous metal and amuie covering the said t-ubes is not herein claimed, broadly, as it forms the subject-matter of another application, Serial No.274,658, filed May Q,V 1888.

I claiml. In a heating apparatus or burner, a hollow base or reservoir provided with a gas or vapor inlet, and a plurality of independent burners attached thereto and communicating with said hollow base or reservoir, and each composed ot' an outer and inner foraminous tube, a base or support therefor, and a inutile supported by said tube, combined with a hollow casting or radiator supported above the independent burners and provided with openings for the passage of heat arising from the burners, substantially as described.

2. In a heating apparatus or burner, the combination, with a hollow base or reservoir provided with a gas or vapor inlet and with an air-passage A', and a wall to separate said reservoir into compartments A2 A, of a plurality of independent burners attached to the upper side of said reservoir about the air-passage A and a hollow casting or radiator supported above the independent burners and provided with heat-outlets, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
